Stats/ probablity problem...help!!?

Question

Hello,
the problem goes like this:
the marketing manager of a food manufacturing company is planning to introduce a new breakfast cereal into the market. In the past 40% of cereals introduced have been successful, and 60% have been failures. Before the cereals were actually marketed, market research was conducted and the report was compiled. 80% of the cereals received favorable report 30% received unfavorable report . the marketing manager wants to know the probability that the new cereal will be successful if it received a favorable report.

thank you!!!

Answer 1

80% of the cereals received favorable report 30% received unfavorable report = 110%, so the problem is worded wrong

Anyhow, 80% had favorable report, but only 40% were successful, so 50% of the time when a cereal has a favorable report, it is successful.

Given that, 50%.
